Medium and heavy duty bus and truck engines are large energy consumers and therefore, significant green house gas generators. Multipoint diesel dual fuel (MDDF) transport engines which utilize a fuel management system that can easily retrofit diesel engines to use natural gas, combine the cleanliness of the natural gas engine with the high fuel efficiency of the diesel engine. This paper uses both, dynamometer tested and field operating engine data (obtained by AFS) to demonstrate the advantages of multipoint diesel dual fuel engines in fuel consumption, green house gas emission and economics compared to 100% CNG stoichiometric and 100% CNG lean burn Otto cycle, and diesel four stroke engines, during their application in bus fleet operating duty cycles. Multipoint diesel dual fuel engine management systems deliver accurate diesel and natural gas fuel quantities to each cylinder, in the course of engine operations. This accurate mode of fuel delivery in MDDF engines causes better fuel efficiency, lesser green house gas emission and favorable operating economics. It is to be shown that MDDF engines are better in fleet operations because they contribute to energy conservation, higher air quality and lesser operating cost. These engines also require the lowest incremental cost for incremental carbon removal from the atmosphere.
